Alrighty, thank you both so much! I managed to figure out most of them and found that they aren't all very hard once you understand the basic concepts. Thanks

Oops! For the second equation, the sad face should be = then bracket...

Hello everyone, I was wondering if someone could help me prove a couple trig identities for am assignment?
Here they are:
(cosx/1+sinx) + (cosx/1-sinx)= 2/cosx
(cosx/1+sinx)=(1-sinx/cosx)
(sinx+tanx/cosx+1)=tanx
1+(sinx+cosx)(cosx-sinx)=2cos*squared*x
(cosx+sinxtanx)/tanx=1/sinx
1/sin*squared*x + 1/ cos*squared*x = 1/sin*squared*xcos*squared*x
I know it's a lot and I hope it's not too confusing the the squares and whatnot.
Help would be greatly appreciated!
Thanks :)
